Descriptions

Simple circular gauge used for the measurement of actual (total gaseous) pressure.

The dial from reads 0 to 50 PSI / 0 to 3.5 x 105 Pa

The case has a clear Perspex back so that the working parts may be seen.

A tubule around 8mm diameter provides connection to the system under investigation.

Overall Dimensions: 100mm (L) x 100mm (W) x 150mm (H)

Diameter: 100mm

Learning Outcomes:

Key Stage 3 Chemistry - The particulate nature of Matter: The properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure.

Key Stage 4 Physics - The Structure of Matter: Links between pressure and temperature of a gas at constant volume, related to the motion of its particles (qualitative).  Explain why the work done in the compression or expansion of gases is the product of the pressure and the change in volume.
